Abstract
A tool for an excavator has a primary engagement arrangement, a secondary engagement arrangement rotatable about an axis of rotation, and a connection arrangement for connecting the tool to an excavator. The axis of rotation of the secondary engagement arrangement passes through the connection arrangement and aligns with the axis of rotation of the tool relative to the excavator. The tool has two hydraulic actuators. The secondary engagement arrangement and the primary engagement arrangement mutually rotate about the same axis of rotation by the hydraulic actuators.
Claims19
A tool for an excavator, the tool comprising:
- a primary engagement means;
- a secondary engagement means rotatable about an axis of rotation;
- and a connection means for connecting the tool to an excavator, wherein the axis of rotation of the secondary engagement means passes through the connection means and aligns with an axis of rotation of the tool relative to the excavator;
- at least one actuation means wherein the at least one actuation means is a hydraulic actuator which is connected to the primary engagement means at one end and the secondary engagement means at other end for moving the tool between an open and closed position;
- wherein the secondary engagement means and primary engagement means mutually rotate about the same axis of the rotation by the same actuation means mounted on the primary engagement means;
- wherein the connection means comprises one or more mounting members;
- wherein the at least one actuation means is connected to the primary engagement means via a mounting pin located in at least one mounting plate mounted on the primary engagement means;
- wherein the one or more mounting plates are located spaced apart from the connection means;
- wherein the secondary engagement means comprising a plurality of engagement elements;
- wherein the at least one actuation means is connected to the secondary engagement means via a further mounting pin located in at least one engagement element;
